The bibliography is easily searchable by author, category, keyword and is on a secure site. We estimate these 2000+ references represent about 2% of all arsenic references, hence we shall be continually adding references. The criterion for inclusion is simply that the document must be primarily focused on arsenic. There are a few exceptions, but only when they contain the sole information on arsenic for the subject area or when they contain compilations with closely associated elements (such as antimony, selenium, and tellurium) and no other data exists.

Undoubtedly some of your favorite references are not included or you may discover editing mistakes. Please send your comments or recommended references to me (dkn@usgs.gov) and we shall try to accommodate you. We hope this bibliography may continue to grow and serve the needs of the research community.
